It’s a Tuesday night in suburban anywhere, USA. A high school junior named Alex opens their backpack. Inside, crumpled between a biology textbook and a half-eaten granola bar, is a single, double-sided worksheet.
At the top, in a clean, no-nonsense font, it reads: Factoring: A "Big Old" Factoring Worksheet Name___________________________________ Date________________ The title alone is ominous. Why is "Big Old" in quotes? Is it mocking you? Below, 60 problems stretch from #1 to #60. No pictures. No cartoons. Just polynomials.
By problem #18, doubt creeps in: 3x³ + 24 . GCF of 3 gives 3(x³ + 8) . Wait — sum of cubes! 3(x+2)(x² - 2x + 4) . Phew. Kuta Software Algebra 2 Big Old Factoring Worksheet
The next day in class, Ms. Garcia says, "Now, before the factoring quiz… let's review the 'Big Old' worksheet."
She also knows that students will search for answer keys online. Kuta Software sells answer sheets to teachers, but students often find scanned copies on Quizlet or Course Hero. She doesn't mind — "Even if they peek, they still have to understand the steps." Alex finishes at 11:47 PM. The worksheet is filled with arrows, scratched-out terms, and tiny numbers from the quadratic formula. They check the back: the last problem is x⁸ - y⁸ — which factors down to (x⁴+y⁴)(x²+y²)(x+y)(x-y) . Alex writes it, closes the notebook, and stares at the ceiling.

Problem #25: 16x⁴ - 81 . Difference of squares? Yes: (4x² - 9)(4x² + 9) . Then the first factor is difference of squares again: (2x-3)(2x+3)(4x²+9) . Check!
But then comes : x⁵ - x³ - 8x² + 8 . Grouping? Try: x³(x² - 1) - 8(x² - 1) . Factor out (x²-1) : (x²-1)(x³ - 8) . Then (x-1)(x+1)(x-2)(x²+2x+4) . Alex writes the answer, erases it twice, then writes it again, heart pounding. At the top, in a clean, no-nonsense font,
A collective groan rises from 28 students. Years later, in college calculus, Alex sees: "Factor x⁴ - 16 to simplify this limit." Without hesitation, Alex writes (x²+4)(x+2)(x-2) . The person next to them asks, "How did you do that so fast?"
